	Well, I could speculate several reasons that itoa() is worth
coded...

1.	It's mucsimpler and faster:  itoa(buffer, 123) is niftier
	than sprintf(buffer, "%d", 123)
2.	Return value.  sprintf() returns number of chars written according
	to ANSI specs.  And itoa() returns ptr to the string written
	for most of the implementations posted here, including my own
	version (or itoa() might need only one argument if it has
	static buffer inside of it).

	It would be definitely useful if you want to code (fs)printf()
by yourself.  Wierd thing is that atoi() exists for scanf but itoa()
doesn't seem to exist in C standard library.  Does anyone know why?
